1％输出纹波，小型解决方案尺寸

IW1699B通过将输出电压幅度降低到12V输出电压的输出电压纹波来提高对话的IW1699 AC / DC控制器的性能，将VCC输入电压范围增加到高达25V，并提高了额外保护功能的鲁棒性。

The iW1699B easily meets the US DoE’s external power supply efficiency standard and the EU’s Code of Conduct, version 5, tier 2 external power supply standard, with no-load power consumption less than 30mW while complying with minimum active mode efficiency requirements.

The iW1699B also incorporates Dialog’sSmartDefender™smart hiccup technology to help address soft short circuits in cables and connectors. Learn more about SmartDefender advanced hiccup technology这里.

IW1699B是销钉和向后兼容IW1699.
